Does GSN have the full show, or do they only have one season? Thanks to whomever can answer.

From what we know, GSN has the full run in their possession as they've aired all the syndie seasons in the past. It's just that since Liberty Media bought 50% of GSN that they have to pay Sony for the shows they want to air, and usually just lease one season at a time.

Which has been the case with a few of GSN's shows. I swear, how many times can you show the '98 season of Win Ben Stein's Money? It's quite annoying.

Generally, they've always just licensed 200 episodes or so of any long-running outside acquisition with an option to pick them up later. I know why they do it (it's expensive to pick up 1,000 episodes of anything with no guarantee of success and it's not worth that big of an investment when most viewers treat GSN as something to watch when nothing else is on), but I understand your feeling.
